Removal and Installation
HP DesignJet 430, 450C and 455CA Printers
Installation
1.
Reinsert the pinchĆarm assemblies into the chassis. Make sure that the
bushings are correctly inserted in the holes.
2.
Slide the bar cam (item 3) to the right. You must position it
between
the
left and right sideĆplates, or the lift mechanism will not work.
In the following step, do not overtighten the camĆjournal screw. Doing
so could break the journal, cause the bar cam to enter the sideĆplate
hole, and thus restrict the action of the pinchĆarm lever.
3.
Before repositioning the right camĆjournal (item 2), tighten its nut just to
the point where the nut is inside the journal. Reinstall the journal and
slightly tighten the screw (item 1).
